FIG. 1 illustrates a first aspect of a fluid testing system 100according to the present disclosure. According to example aspects, thefluid testing system 100 can be configured to test one or morecharacteristics of fluid from a fluid piping system (not shown). In afirst example aspect, the fluid testing system 100 may be configured totest the quality of the fluid; for example, the fluid testing system 100may measure levels of lead, bacteria, nitrates, chlorine, pH levels, orthe like. The fluid piping system can be any fluid-carrying system, suchas, for example, a potable water system. In other aspects, the fluidpiping system can be another type of water supply system, a natural gassystem, a sewage system, an irrigation network, or the like. In someaspects, the fluid testing system 100 can also or alternatively beconfigured to measure the pressure of the fluid in the fluid pipingsystem. Furthermore, in various aspects, the fluid testing system 100may be able to wirelessly relay information related to the fluidpressure, or other measured characteristics, to a third party or anexternal device (e.g., an operations center, a computer, a phone, etc.),as described in further detail below. In other aspects, the fluidtesting system 100 may be configured to measure other characteristics ofthe fluid.

According to example aspects, the fluid testing system 100 can comprisea pit assembly 110 and a sampling station assembly 140. As shown,example aspects of the pit assembly 110 can comprise a pit housing 115.The pit housing 115 can comprise a pit liner 120 and a pit lid 125.Other aspects of the pit housing 115 may not comprise the pit lid 125and may comprise the pit liner 120 only. As shown, the pit lid 125 canbe secured to the pit housing 115 by one or more fasteners 130. Forexample, the fasteners 130 can be screw and bracket assemblies 132 orany other suitable fasteners known in the art, including, but notlimited to, nut and bolt assemblies, welding, adhesives, and the like.The pit housing 115 can be configured to house and protect variouscomponents therein. For example, the pit housing 115 can be configuredto house and protect a curb stop assembly 200 (shown in FIG. 2) forselectively shutting of fluid flow to the sampling station assembly 140.Example aspects of the pit housing 115 can also be configured to house apressure transducer 290 (shown in FIG. 2) for measuring the pressure ofthe fluid in the fluid piping system, as shown and further describedbelow.

The pit liner 120 and the pit lid 125 can be formed from a substantiallyrigid material, such that the components mounted therein can besufficiently protected. For example, the pit liner 120 and pit lid 125can be formed from a metal material, such as steel. In other aspects,the pit liner 120 and pit lid 125 can be formed from any other suitablyrigid material material, including, but not limited to, plastics andother types of metal, or any suitable combination thereof. In exampleaspects, the pit liner 120 and the pit lid 125 can be formed from thesame material, while in other aspects, the pit liner 120 and the pit lid125 can be formed from varying materials. In example aspects, the pithousing 115 can be installed below-grade (i.e., below ground level 180),and the pit lid 125 can be about flush with the ground level 180. Otheraspects of the pit assembly 110 can be installed fully or partiallyabove-grade (i.e., above ground level 180).

As shown, according to various example aspects of the fluid testingsystem 100, in the present aspect, the sampling station assembly 140 canbe attached to the pit assembly 110 at a top end 112 thereof. In oneaspect, the sampling station assembly 140 can be a Mueller Co.Hydro-Guard® Sampling Station, for example, the Hydro-Guard® Blow-OffSampling Station. In the present aspect, the sampling station assembly140 can be an above-grade station; however, in other aspects, thesampling station assembly 140 can be a below-grade station. Exampleaspects of the sampling station assembly 140 can comprise a samplingstation housing 145. The sampling station housing 145 can comprising asampling station liner 150 and a sampling station lid 155. In variousaspects, the sampling station lid 155 can be hingedly coupled to thesampling station liner 150 by a lid hinge 255 (shown in FIG. 2), suchthat the sampling station lid 155 is pivotable between a closedposition, as shown in FIG. 1, and an open position, as shown in FIG. 2.In other aspects, the sampling station lid 155 may not be hingedlycoupled to the sampling station liner 150. According to some exampleaspects, a pressure monitor 170 may be coupled with sampling station lid155, as will be described in further detail below. In other aspects, thepressure monitor 170 may be positioned elsewhere on or within the fluidtesting system 100, and other aspects may not comprise a pressuremonitor 170.

As shown, the sampling station assembly 140 can be secured to the pitassembly 110. For example, the sampling station liner 150 can be securedto the pit lid 125, such that, in the present aspect, the samplingstation assembly 140 can be stacked on the pit assembly 110, as shown.Thus, in the present aspect, the sampling station assembly 140 can beinstalled substantially above-grade. Other aspects of the samplingstation assembly 140 may be installed fully or partially below-grade.The sampling station assembly 140 can be secured to the pit assembly 110by a fastener, such as, for example, screws, nuts and bolts, adhesives,welding, or any other suitable fastener known in the art. In otheraspects, the sampling station assembly 140 may be connected to the pitassembly 110 elsewhere on the pit assembly 110 or may not be connectedto the pit assembly 110 at all.

The sampling station housing 145 can be configured to house and protectvarious components therein, as described in further detail below. Assuch, the sampling station liner 150 and sampling station lid 155 can beformed from a substantially rigid material, such that the componentsmounted therein can be sufficiently protected. For example, the samplingstation liner 150 and sampling station lid 155 can be formed from ametal material, such as steel. In other aspects, the sampling stationliner 150 and sampling station lid 155 can be formed from any othersuitably rigid material, including, but not limited to, plastics andother types of metal, or any suitable combination thereof. In exampleaspects, the sampling station liner 150 and sampling station lid 155 canbe formed from the same material, while in other aspects, the samplingstation liner 150 and the sampling station lid 155 can be formed fromvarying materials.

FIG. 2 illustrates the pit liner 120 of the pit housing 115 astranslucent for visibility of components mounted within the pit housing115. FIG. 2 also illustrates the sampling station lid 155 pivoted to theopen position. As shown in FIG. 2, example aspects of the pit assembly110 can comprise the curb stop assembly 200, which can be in fluidcommunication with the fluid piping system as described in furtherdetail below, and which can allow a user to selectively start and stopthe flow of fluid through a curb stop valve 205 of the curb stopassembly 200. The curb stop valve 205 can be, for example, a ball valve,a butterfly valve, or any other suitable type of valve known in the art.According to example aspects, a portion of the curb stop assembly 200can be received within the pit housing 115, along with the pressuretransducer 290, for protection from undesirable external factors, suchas dirt and moisture, heavy impacts, tampering, and the like.

As shown, example aspects of the pit liner 120 can define an inner pitliner surface 222 and an outer pit liner surface 224. The inner pitliner surface 222 can define an interior pit cavity 230 within which thecurb stop assembly 200 and pressure transducer 290 can be mounted.Example aspects of the pit liner 120 can be formed from substantiallyrigid material, such as a metal material, such that the componentsmounted within the pit housing 115 can be protected, as described above.In example aspects, the pit liner 120 can comprise a substantiallycylindrical pit sidewall 235. In other aspects, the pit sidewall 235 candefine any other suitable shape. For example, the pit sidewall 235 candefine a rectangular cross-sectional shape or any other suitablecross-sectional shape. Moreover, the pit sidewall 235 can define a firstpit end 236 and a second pit end 238, each of which can be open and canallow access to the interior pit cavity 230.

The pit lid 125 can be provided for covering or substantially coveringthe open first pit end 236. As described above, the pit lid 125 can becoupled to the pit sidewall 235 by the screw and bracket assemblies 132or any other suitable fastener 130. In some example aspects, the pit lid125 can be lockable to prevent accidental or intentional tampering withthe components within the interior pit cavity 230 (e.g., the pressuretransducer 290 and curb stop assembly 200); however, in other aspects,the pit lid 125 may not be lockable. Furthermore, according to exampleaspects, the pit lid 125 can define a pit lid opening 425 (shown in FIG.4) formed therethrough, which can provide access to the interior pitcavity 230 and which will be described in further detail below.Furthermore, in some aspects, the second pit end 238 opposite the pitlid 125 may not be completely open. For example, in some aspects, thepit liner 120 can comprise a pit end wall (not shown) oriented at thesecond pit end 238. The pit end wall can be semi-permeable, such thatliquids can drain out of the pit liner 120 through the pit end wall, butsolids such as dirt cannot enter the interior pit cavity 230 through thepit end wall. In other aspects, however, the pit end wall may provide awatertight seal with the pit sidewall 235, such that fluid cannot enteror exit the interior pit cavity 230 through the second pit end 238.

Example aspects of the sampling station liner 150 can define an innerstation liner surface 652 (shown in FIG. 6) and an outer station linersurface 254. The inner station liner surface 652 can define an interiorsampling station cavity 660 (shown in FIG. 6) within which variouscomponents can be housed and protected. In the present aspect, thesampling station liner 150 can comprise a sampling station sidewall 265having the shape of a rectangular prism. In other aspects, the samplingstation sidewall 265 can define any other suitable shape, including, butnot limited to, cylindrical. The sampling station liner 150 can furthercomprise a sampling station door 240 hingedly coupled to the samplingstation sidewall 265 by a door hinge 242. The sampling station door 240can be opened to allow access to the interior sampling station cavity660 or closed to prohibit access to the interior sampling station cavity660. The sampling station sidewall 265 can define a first samplingstation end 266 and a second sampling station end 268, and the samplingstation lid 155 can be oriented at the first sampling station end 266,such that access to the interior sampling station cavity 660 at thefirst sampling station end 266 can be limited or prohibited when thesampling station lid 155 is closed. A sampling station opening (notshown) can be defined at the second sampling station end 268, such thatthe second sampling station end 268 is open and allows access to theinterior sampling station cavity 660. In example aspects, the pit lidopening 425 can be substantially aligned with the sampling stationopening to allow various components of the fluid testing system 100 toextend between the interior pit cavity 230 and the interior samplingstation cavity 660.

According to example aspects, a pit access opening 270 can be providedthrough the pit sidewall 235 as shown. In other aspects, the pit accessopening 270 can be provided through the pit end wall, if present. Asshown, an inlet conduit 272 can extend through the pit access opening270 to connect the fluid piping system to the components mounted withinthe interior pit cavity 230. For example, the inlet conduit 272 canallow the fluid piping system to be in fluid communication with the curbstop assembly 200. As shown, the curb stop assembly 200 can be installedbelow-grade (i.e., below ground level 180) within the pit housing 115 ofthe pit assembly 110.

Example aspects of the curb stop assembly 200 can comprise a curb stopvalve 205, a curb stop guide 210, a curb stop sleeve 212, and a curbstop rod 315 (shown in FIG. 3). The curb stop valve 205 can define avalve inlet end 206, a valve outlet end 208, and a fluid passageway (notshown) therebetween, and the valve inlet end 206 can be connected to theinlet conduit 272. The curb stop guide 210 can be generally positionedatop the curb stop valve 205, relative to the orientation shown, and canguide the curb stop rod 315 into engagement with the curb stop valve205. In example aspects, the curb stop rod 315 can engage a valve cap312 (shown in FIG. 3), which can be housed within the curb stop guide210 and which can be movable relative to the curb stop valve 205 betweena closed orientation, wherein the curb stop valve 205 is closed andfluid is prevented from flowing through the curb stop valve 205, and anopen orientation, wherein the curb stop valve 205 is open and fluid ispermitted to flow through the curb stop valve 205. The curb stop sleeve212 can extend generally upward from the curb stop guide 210, relativeto the orientation shown. The curb stop rod 315 can be housed within thecurb stop sleeve 212 and can be connected to the valve cap 312 by afastener, such as, for example, a clevis fastener, or any other suitablefastener known in the art. The curb stop rod 315 can be accessed througha sleeve opening 414 (shown in FIG. 4) at an upper section 413 (shown inFIG. 4) of the curb stop sleeve 212 distal from the curb stop guide 210.According to example aspects, the curb stop sleeve 212 can extendthrough the pit lid opening 425 and the sampling station opening, suchthat the upper section 413 of the curb stop sleeve 212 can extend intothe interior sampling station cavity 660.

According to example aspects, the curb stop assembly 200 can be operatedto open and close the curb stop valve 205 to selectively allow orprohibit fluid flow therethrough from the valve inlet end 206 to thevalve outlet end 208. In one aspect, a user can engage a tool (notshown), such as a key, with the curb stop rod 315 at a rod key end 416(shown in FIG. 4) thereof. The key or other tool can be manually rotatedto rotate the curb stop rod 315 within the curb stop sleeve 212, whichcan in turn rotate (or otherwise move) the valve cap 312 to which thecurb stop rod 315 is connected. The valve cap 312 can be rotated to theclosed orientation to close the curb stop valve 205 or to the openorientation to open the curb stop valve 205, depending upon thedirection in which the key is turned.

Example aspects of the fluid testing system 100 can further comprise asampling pipe 280 connected to the curb stop valve 205 at the valveoutlet end 208, opposite the inlet conduit 272, as shown. In the presentaspect, the sampling pipe 280 can generally define an L-shape, having asubstantially horizontal pipe segment 282 extending from the valveoutlet end 208 and a substantially vertical pipe segment 284 extendinggenerally upward from the horizontal pipe segment 282. The horizontaland vertical pipe segments 282,284 can be linked together by a bend pipefitting 286. According to example aspects, fluid from the fluid pipingsystem can pass through the curb stop valve 205 when the valve 205 isopen and can travel up the sampling pipe 280, relative to theorientation shown. An upper section 484 (shown in FIG. 4) of thevertical pipe segment 284 of the sampling pipe 280 can extend into theinterior sampling station cavity 660, and fluid samples can be collectedfrom the sampling pipe 280 within the sampling station assembly 140, aswill be described in further detail below.

In some aspects of the sampling station assembly 140, the samplingstation lid 155 can define a sampling station lid hole 256 therethroughand the pressure monitor 170 can be coupled thereto. In the presentaspect, the pressure monitor 170 can define a lower portion 276configured to be received through the sampling station lid hole 256 andto extend into the interior sampling station cavity 660 and an upperportion 278 positioned outside of the interior sampling station cavity660. In other aspects, the upper portion 278 of the pressure monitor 170can be positioned inside the interior sampling station cavity 660. Theupper portion 278 of the pressure monitor 170 can comprise an antenna(not shown) housed within that can be configured to send signals to athird party or device (e.g., an external operations center of a utilitycompany) related to the measured pressure of the fluid in the fluidpiping system. In some aspects, the sampling station housing 145 can beformed from a ferrous material, such as, for example and withoutlimitation, stainless steel. The upper portion 278 of the pressuremonitor 170 comprising the antenna can be oriented outside of thesampling station housing 145 such that the ferrous material will notinterfere with signals sent by the antenna. In other aspects, thesampling station housing 145 can be formed from non-ferrous materials,or a combination of ferrous and non-ferrous materials. Furthermore,other aspects of the fluid testing system 100 may not comprise thepressure monitor 170.

FIG. 3 illustrates a detail view of the inlet conduit 272, pressuretransducer 290, and the curb stop valve 205. According to exampleaspects, the pressure transducer 290 can be positioned on the inletconduit 272 between the fluid piping system and the curb stop valve 205,as shown. In other aspects, the pressure transducer 290 can bepositioned elsewhere within the fluid testing system 100. In someaspects, a bulkhead fitting (not shown) can be installed on the inletconduit 272 and the pressure transducer 290 can be connected to thebulkhead fitting. The pressure transducer 290 can be any suitable typeof pressure transducer 290, such as a strain gauge pressure transduceror any other pressure transducer known in the art. According to exampleaspects, the pressure transducer 290 can be configured to measure thepressure of the fluid in the inlet conduit 272 from the fluid pipingsystem. In some aspects, fluid from the fluid piping system can bereceived in the inlet conduit 272 even when the curb stop valve 205 isclosed, and as such, the pressure transducer 290 can be configured tomeasure the pressure of the fluid when the curb stop valve 205 is bothopened and closed. Some aspect of the pressure transducer 290 canfurther be configured to generate an electrical signal representative ofthe measured pressure. The pressure transducer 290 can becommunicatively coupled to the pressure monitor 170, such that theelectrical signal can be relayed to the pressure monitor 170 (shown inFIG. 1). For example, the pressure transducer 290 can be communicativelycoupled to the pressure monitor 170 by a wire, and the data can betransmitted from the pressure transducer 290 to the pressure monitor 170through the wire. In other aspects, the pressure transducer 290 can bewirelessly coupled to the pressure monitor 170 for the transmission ofdata (e.g., via Bluetooth®.) As described above, the antenna of thepressure monitor 170 can then send signals to a third party related tothe pressure data. For example, the fluid testing system 100 may sendalerts to a third party when notable spikes or drops in pressure aredetected. According to example aspects, the pressure transducer 290 canbe within the pit housing 115 for protection from undesirable externalfactors, such as dirt, moisture, heavy impacts, tampering, and the like.

As shown, the curb stop guide 210 is illustrated as transparent forvisibility of the components therein. As described above, the curb stopguide 210 can guide the curb stop rod 315 into engagement with the valvecap 312. According to example aspects, a drain 310 can be provided on abottom side 306 of the curb stop valve 205, as shown. The drain 310 canbe in fluid communication with the fluid passageway of the curb stopvalve 205. Example aspects of the drain 310 can allow excess fluidreceived within the sampling pipe 280 and curb stop valve 205 to drainout of the fluid testing system 100 at the second pit end 238 of the pitassembly 110. Draining the excess fluid out of the fluid testing system100 can aid in preventing damage to the curb stop assembly 200 and/orsampling pipe 280 that can be caused by the excess fluid freezing withinthese components during low temperatures. The excess fluid can bedrained out through the drain 310 after fluid samples are taken throughthe sampling pipe 280 or after the fluid piping system is flushed, theprocesses for which is described in further detail below.

In some aspects, the fluid testing system 100 can comprise a pair ofretaining nuts 320 configured to aid in securing the inlet conduit 272to the pit sidewall 235 (shown in FIG. 2) at the pit access opening 270(shown in FIG. 2). As shown, the inlet conduit 272 can define a threadedportion 372 which can be configured to threadably engage a correspondingthreaded opening (not shown) formed in each of the retaining nuts 320.In example aspects, a first one of the retaining nuts 320 can beconfigured to abut the inner pit liner surface 222 (shown in FIG. 2) ofthe pit liner 120 (shown in FIG. 2) and a second one of the retainingnuts 320 can be configured to abut the outer pit liner surface 224(shown in FIG. 2) of the pit liner 120. The retaining nuts 320 can besufficiently tightened against the inner and outer pit liner surfaces222,224 to secure the inlet conduit 272 in position relative to the pitliner 120.

FIG. 4 is a top perspective view of the pit assembly 110, illustratingthe pit lid 125 of the pit housing 115. As shown, the pit lid 125 candefine the pit lid opening 425 formed therethrough, which can allowaccess to the interior pit cavity 230. In the present aspect, the uppersection 413 of the curb stop sleeve 212 and an upper section 484 ofvertical pipe segment 284 of the sampling pipe 280 can extend throughthe pit lid opening 425 and into the interior sampling station cavity660 (shown in FIG. 6) of the sampling station assembly 140 (shown inFIG. 1). In various aspects, one or more retaining bracket 450 can beprovided for retaining the vertical pipe segment 284 of the samplingpipe 280 and the curb stop sleeve 212 in position in an uprightorientation. For example, the vertical pipe segment 284 can pass througha pipe retaining hole 460 formed in the retaining bracket 450, and thecurb stop sleeve 212 can pass through a sleeve retaining hole 455 formedin the retaining bracket 450, as shown. The retaining bracket(s) 450 canbe positioned within the interior sampling station cavity 660 when thesampling station assembly 140 is mounting to the pit assembly 110. Otheraspects can comprise more retaining brackets 450, and still otheraspects may not comprise retaining brackets 450. Furthermore, in someaspects, the retaining bracket(s) 450 can be positioned alternatively oradditionally within the interior pit cavity 230.

In the present FIG. 4, the curb stop rod 315 can be seen housed withinthe curb stop sleeve 212. As shown, the curb stop sleeve 212 can definethe sleeve opening 414 through which the curb stop rod 315 can beaccessed. The curb stop rod 315 can define the rod key end 416positioned proximate the sleeve opening 414. In example aspects, asdescribed above, a user can manually engage the rod key end 416 of thecurb stop rod 315 with a tool, such as a key, to actuate the curb stoprod 315. For example, the key may be used to rotate the curb stop rod315. Rotating the curb stop rod 315 can rotate the valve cap 312 toselectively open or close the curb stop valve 205. When the curb stopvalve 205 is opened, fluid can flow through the curb stop valve 205 fromthe fluid piping system to the sampling pipe 280. Samples of the fluidcan be taken from the sampling pipe 280 or the fluid can be flushedthrough a blow-off assembly 590 (shown in FIG. 5), as described infurther detail below.

FIG. 5 illustrates the sampling station assembly 140 with the samplingstation liner 150 (shown in FIG. 1) removed for visibility of thecomponents received/mounted within the interior sampling station cavity660 (shown in FIG. 6). As illustrated, the upper portion 278 of thepressure monitor 170 can extend above the sampling station lid 155,relative to the orientation shown, such that it is positioned outside ofthe interior sampling station cavity 660, while the lower portion 276 ofthe pressure monitor 170 can extend through the sampling station lid 155and into the interior sampling station cavity 660. As shown, anotherretaining bracket 450 can be positioned proximate to the sleeve opening414 of the curb stop sleeve 212 and can aid in further retaining thecurb stop sleeve 212 and the vertical pipe segment 284 of the samplingpipe 280 in the upright orientation.

According to example aspects, a sampling assembly 505 can be oriented onthe upper section 484 of the vertical pipe segment 284, as shown. Thesampling assembly 505 can be configured to dispense samples of fluidfrom the sampling pipe 280 for testing the quality of the fluid. Forexample, as described above, the fluid can be tested for levels of lead,bacteria, nitrates, chlorine, pH levels, or the like. A sampling valve510 can be connected to the sampling pipe 280 for transmitting fluidfrom the sampling pipe 280 to a sampling dispenser 515 through which thefluid can be dispensed. The fluid can be dispensed into a collectioncontainer and can be tested on site or taken to a testing facility.Example aspects of the sampling assembly 505 can further comprise asampling actuator 520 configured to open and close the sampling valve510 to selectively allow or prevent fluid flow through the samplingdispenser 515, respectively. In the current aspect, the samplingactuator 520 is a handle on the sampling valve. As such, to obtain afluid sample of the fluid in the fluid piping system, the valve cap 312can be moved to the open orientation to open the curb stop valve 205 andallow fluid to flow from the fluid piping system into the inlet conduit272 and through the open curb stop valve 205. The fluid can flow fromthe valve inlet end 206 to the valve outlet end 208 of the curb stopvalve 205 and into the sampling pipe 280. The sampling actuator 520 canbe actuated to open the sampling valve 510, to allow fluid to flow fromthe sampling pipe 280 through the sampling valve 510 and into thesampling dispenser 515. The sampling dispenser 515 can then dispense thefluid into a collection container for testing.

According to example aspects, the sampling pipe 280 can further comprisethe blow-off assembly 590 configured to flush out contaminated fluidfrom the fluid piping system. As shown, the blow-off assembly 590 can beoriented at an upper pipe end 586 of the vertical pipe segment 284 ofthe sampling pipe 280. The blow-off assembly 590 can define a curvedsection 594 formed in the vertical pipe segment 284 and a blow-offopening 592 through which fluid can be expelled. The fluid piping systemcan be flushed to expel fluid tainted with undesirable contaminants,like bacteria, or having undesirable levels of various substances,including, but not limited to lead, nitrates, chlorine, etc. The fluidcan be can be flushed for any other suitable purpose, as well. Invarious aspects, the sampling station door 240 of the sample stationliner 150 can be pivoted open about its corresponding door hinge 242 sothat the fluid can be expelled out of the sampling station assembly 140and into the external surroundings. According to example aspects, ablow-off valve 595 can be provided within the vertical pipe segment 284which can be selectively opened and closed to allow and prevent,respectively, fluid flow out of the blow-off opening 592. As shown, theblow-off valve 595 can comprise a blow-off actuator 596, which can beoperated to open and close the blow-off valve 595. In various aspects,sampling valve 510 and the blow-off valve 595 can each be, for example,a ball valve, a butterfly valve, or any other suitable type of valveknown in the art.

The curb stop sleeve 212 is alsoillustrated as transparent for visibility of the curb stop rod 315housed therein. As shown, the pit assembly 110 can be installedsubstantially below-grade (i.e., below ground level 180), and the pitlid 125 can be about flush with ground level 180. The pressuretransducer 290 and the curb stop valve 205 can be mounted within theinterior pit cavity 230 of the pit housing 115 for protection fromundesirable external factors, including, but not limited to, dirt,moisture, impacts, tampering, and the like. Furthermore, the samplingstation assembly 140 can be installed substantially above-grade (i.e.,above ground level 180). The blow-off assembly 590, sampling assembly505, and the lower portion 276 of the pressure monitor 170 can bemounted within the interior sampling station cavity 660 of the samplingstation assembly 140 for protection from undesirable external factors,including, but not limited to, dirt, moisture, impacts, tampering, andthe like. According to example aspects, the curb stop sleeve 212 and thecurb stop rod 315 housing therein can extend between the interior pitcavity 230 and the interior sampling station cavity 660, and thevertical pipe segment 284 of the sampling pipe 280 can extend betweenthe interior pit cavity 230 and the interior sampling station cavity660.
